Re: King 7S 3D phone on sale!

7S owners please test your ghosting.

I made two SBS pictures, left eye with different grey circles, right eye is black (picture 1), or grey (picture 2).

0. Download these files to the phone:

Pic 1

Pic 2

1. Set your brightness to maximum on PPTV.

2. Open 3DSteroid, set stereo mode to 3DLCD.

3. Press Menu/Open File, check one picture, hit OK.

4. If the bottom menu is still visible, touch center of the screen.

Now you can start testing the ghosting.

5. Close one of your eyes, hold the phone in your hands and rotate a little left to right (around the Y axis).

6. If you move away from you to the max, you will see a big dark "ghost" moving left to right as you rotate. Slowly move the phone closer to your head. You will find a position where this "ghost" fill the entire screen. That's your best distance for 3D, by me around 30cm. If you move even closer, it will be worse again.

7. Now check which dark circle is the first visible, when the entire screen is at darkest.

By me it's the number 3 on the 2nd line. That means big ghosting
Picture "Ghost2" has less contrast, because the background is not total black, just grey.

Here i see circle 5 or 6.

How about you? Is all PPTV the same, or should i order another?
I made this test because i discover ghosting in 80% of my pictures
All my other 3D displays are much better (dlp projectors, lg 3dtv or even my old 2342 lg monitor show ghosting from circle 6 (pic1) and 16 (pic2), which is way better than this screen.
Thanks for checking
